摘要：

The CDF and DO Collaborations have both reported unusual events in the dilepton + jets sample with very high lepton and missing transverse energies. It is possible, but very unlikely, that these events originate from top quark pair production; however, they have characteristics that are better accounted for by decays of supersymmetric quarks with mass in the region of 300 GeV: (q) over tilde-->q<(chi)over tilde>, <(chi)over tilde>-->nu (l) over tilde, (l) over tilde-->l<(chi)over tilde(1)(0)> Such a supersymmetric origin also leads to events with large missing transverse energy and either 0, 1, 2 same-sign, or 3 isolated charged leptons.
